9 Claims.

My invention comprises generally a hair waving pad of novel constructionwhich is adapted more particularly for use in permanently wavingcroquignole wound hair, said pad including an outer sheet, an envelopecontaining an exothermic material, van inner sheet and an intermediateabsorbent sheet interposed between the envelope and inner sheet.

My invention more particularly comprises a hair waving pad of the abovecharacter in which the outer sheet is of non-absorbent material, asparchment paper, the envelope is of impervious material as foil, theinner sheet is' of impervious material as foil, and the intermediatesheet is of absorbent material, as cotton fabric; the said inner sheetand envelope being perforated and the said intermediate sheet beingmoistened before the pad is used.

A practical embodiment of my invention is represented in theaccompanying drawings, in which Fig. 1 represents an inside plan view ofthe pad in its unfolded and unwrapped condition, a portion of theimpervious envelope being broken away to disclose the exothermicmaterial within the envelope;

Fig. 2 represents an inside plan view of the pad in its folded andunwrapped condition after the envelope and inner sheet have beenperforated and the intermediate sheet has been moistened; correspondingcorners of the inner and intermediate sheets being turned back;

Fig. 3 represents a side view of an apparatus for permanently wavingcroquignole wound hair with my improved pad in operative positiontherein;

Fig. 4 represents across section taken in the plane of the line IV--IVof Fig. 1;

Fig, 5 represents a top plan view;

Fig. 6 represents an end view;

Fig. 7 represents a side view of the combined clamp and shield formingpart of the apparatus;

Fig. 8 represents an end view of the same;

Fig. 9 represents a top plan view of the combined clamp and shield;

Fig. 10 represents a'crosssection taken in the plane of the line X-X ofFig. 9, looking in the direction of the arrows; and

Fig. 11 represents a top plan view of the combined clamp and shieldinits opened position.

The outer sheet i of my improved pad is of some suitable non-absorbentmaterial, such for instance as parchment paper. An envelope 2 of someimpervious material, such for instance as foil, is attached to the innerface of the outer sheet 9. This envelope is somewhat shorter than theouter sheet i, leaving projecting ends for wrapping around the tresswinding mandrel when the pad is put into use. This impervious 5 envelope2 contains a suitable exothermic material 3, such for instance ascalcium oxide in powdered form, which material when moistened will ofitself generate sufiicient heat to impart aso-called permanent wave tothe croquignole 10 wound tress when the pad encloses the same.

An inner sheet 4 of impervious material, such for instance as foil, isattached to the inner face of the outer sheet I at one end thereof.

An intermediate sheet 5 of absorbent mateit rial, such for instance ascotton fabric, is attached to the inner face of the non-absorbent outersheet i at one side thereof and projects from the outer sheet at rightangles to the inner impervious sheet 5. 20

Just before the pad is put into' use the inner sheet 4 and the innerface of the envelope 2 are perforated by means of a suitable implement.The intermediate sheet 5 is moistened, the perforated inner sheet traised from the 25 envelope 2 and the moistened intermediate sheet 5spread over the perforated face of the envelope 2. The perforated innersheet l is then laid over the moistened intermediate sheet 5 and themoisture is caused to enter the perforatedg envelope 2 as by pressingthe whole between the fingers. Due to the moisture the reaction of theexothermic material will start and will generate heat suflicient toimpart a permanent wave to the wound tress to which the pad is applied.

In the present instance I have shown the pad as applied to a hair wavingapparatus which forms the subject matter of my copending applicationfiled of even date herewith, Serial No. 619,024; a brief description ofwhich apparatus 40 follows:

The mandrel 9 on which the tress is to be wound in the croquignolemanner may be of any well known or approved form, its squared end beingdenoted by Hi and its cylindrical end by ii.

The divided tress clamp comprises two sheet metal channelmembers i2 andi3 for receiving and holding the two tress engaging strips itand I5 ofsuitable yielding insulating material. 5 These clamp members It. and 13are developed to form the divided shield, the shield members comprisingthe bottom 16. and I1 and the uprising sides l8 and I9. The clampmembers l2 and l3-are'a1so developed to form the two members and 2| 01.a divided uprising ear having a slot 22 for the reception of thecylindrical end -ll of the mandrel. One of the clamp members, the clampmember l3, for example, is developed at the other end of the clamp toform an uprising ear 23 having a recess .24 for rotatably mounting thesquared end ID of the mandrel 9.

A link 25 forms a hinge connection at one end of the clamp between thetwo clamp members. The other end of the clamp is provided with a link 26pivoted to one of the members, the member I2, for example, which link isprovided with a cam lever 21 for engaging the other member to hold themembers in their closed position.

A pad 28 of felt or other suitable material is inserted between thetress clamp and the scalp.

In practice, the tress may be moistened, if desired, before or after itis wound on the mandrel. After the tress has been wound on the mandrelthe pad -with its moistened intermediate sheet 5 and its perforatedenvelope and inner sheet is wrapped partly around the tress by insertingthe sides of the pad into the shield, the sides of the shield serving tohold the pad in its operative position. It will be understood that theprojecting ends of the outer sheet 4 of the pad are wrapped around themandrel 9 beyond the tress.

As soon as the exothermic material in the envelope becomes moistenedtheexothermic action starts and the heat then set up within the pad impartsa so-called permanent wave to the wound tress.
